Abstract

A lockable sleeve drainage catheter is disclosed for percutaneous insertion into a patient and drainage of fluid therefrom. The drainage catheter includes a flexible distal end (105) that is preformed for retaining the distal end (105) of the catheter that is inserted in the patient. For insertion, the distal end (105) is straightened with the use of a stiffening cannula that is inserted through the hollow passageway (107) of the catheter. When the catheter is inserted in the patient, the stiffening cannula is removed, and a flexible tension member (121) positioned within the passageway (107) of the catheter is drawn to position the distal end (105) in the desired retention configuration. A lockable sleeve (110) positioned at the proximal end (106) of the catheter draws the flexible tension member (121) through the passageway (107) of the elongated member tube (104) to position the distal end (105) in the retention configuration. The catheter also includes a locking collar (114) at the proximal end (106) of the elongated member tube (104) having an annular recess (119) formed therein. The distal end (111) of the lockable sleeve (110) includes an annular step (120) for engaging the recess (119) of the collar (114) and locking the sleeve (110) in a fixed position relative to the elongated member tube (104) of the catheter. When fully extended and locked, the sleeve (110) and elongated member (104) form a fluid tight interconnection. A Luer lock connector (124) is affixed to the proximal end (112) of the sleeve (110) for connection to a drainage collection system. <IMAGE>

いて患者の体に沿って曲げてもよい。When the sleeve 110 is pulled (to the right with respect to the elongate member 104 in FIG. 1), it is engaged and secured in the tubular recess 119 of the elongate member 104 and passes through the passage 107 between the withdrawal ports 122 and 123. The length of the tension member 121 that is stretched in a loop shape becomes shorter. As a result, the tip 105 of the elongated member 104 has a pigtail shape (FIG. 3).
To The retaining disc 129 is secured with a tie 125 around the elongate member 104 on the outer surface of the abdominal wall 130 to securely secure the waste catheter to the patient. The flexible elongate member 104 may be bent along the patient's body using a 90 degree retaining disc (not shown).

と主体の周囲に形成されている。FIG. 4 shows another embodiment of the distal end portion of the waste catheter. In this embodiment, the distal end 401 of the elongate member 402 of the catheter has a known shape that retains the distal end in the patient's bile organ system. A plurality of waste liquid ports 403 and 404 are formed around the distal end of the elongated member 402 and the main body.

用供給チューブとして機能できる。FIG. 5 shows a second alternative embodiment of the distal end of the waste catheter. In particular, the tip 501 of the elongated member 502 is formed in a pigtail shape, with the tip extending further from the curved portion of the pigtail. Such a shape can function as a percutaneously inserted delivery tube for gastric fistula formation.

However, in this embodiment, a waste catheter has been described that can be more easily operated by the patient without connecting a flexible pull member. Once the catheter is in the locked position, the catheter constitutes a closed system that drains fluid from the patient. In addition, one end of the tension member is coupled to the distal end of the elongated member in a known manner and is pulled through a withdrawal port to position the distal end in place.
